This is my job, so I'll counter that this isn't realistic, and in a professional situation it would probably be hosted in kubernetes which spans multiple servers and sometimes multiple regions - I don't think the devs have a readme for that.. (or maybe they do). The point being that the official docs are geared for a hobbyist to set up a node and not having separate VMs makes sense in that scenario. However I would say that it's plain that mister db0 has a much larger instance than could be considered hobbyist at this point.
